Great to see the subject getting more attention - thanks Louis. What I would add regarding natural refrigerants is that most of the barriers are regulatory – not technical. Good example being the billion or so domestic refrigerators out there already running on natural refrigerants – they can scale when there is support and not being hindered by incumbents. We need to turn off the taps on fluorinated refrigerants (including the low-GWP ones with their upstream and downstream chemical pollution) at the same time as cleaning up the mess that is already out there. Otherwise we’re just making things so much harder for ourselves...
